Suppose the amount of bacteria growing in a perti dish is represented by the function b(t)=50t/t+1
Evaluate the function at t=1,2,5,10,15,20 (a) constract a table of values (b) use the table to sketch a graph.

  1. Surely you meant:

    b(t) = 50t/(t+1) or else the t's would just cancel

    b(1) = 50(1)/(1+1) = 51/2 or 25.5
    b(2) = 50(2)/(2+1) = 100/3 = ...
    b(5) = 50(5)/(5+1) = 250/6 = ..
